Leonardo DiCaprio and Carey Mulligan are already locked in for "The Great Gatsby," but there's one more actor dying to be a part of director Baz Luhrmann's upcoming 3-D spectacle: Bradley Cooper.

In a new interview with the New York Times, Cooper lobbies for the role of Tom Buchanan, the cocky blueblood husband of Gatsby's (DiCaprio) love interest, Daisy (Mulligan).

"To me, he's the best character in the book. He's so complicated," says the star of "The Hangover – Part II." "He's xenophobic, he's an alcoholic, but he also understands some profound stuff about class. Whoever plays it has to take a gentle hand, because it could so easily be stock, where he’s a rich jerk you don't identify with at all."

Cooper — who recently showed off his real-life love, Renee Zellweger, during his taping of "Inside the Actors Studio" — then joked that talking about the "Gatsby" gig would probably hurt his chances of landing the role.

"I don't even know if I'm on Luhrmann's radar,” he said. "Maybe he'll read this article after the role's cast and say, ‘Oh. Ha. Yeah, that guy was never going to get it.'"

Meanwhile, Luhrmann insists that his own directing duties for "Gatsby" aren't exactly a done deal.

"Despite what might be out there, I have made no comment about anything," he told Vulture. "So until I say it, it's not said, you know."
